What colour will everything appear through a blue and a cyan filter?
Through a blue filter, objects will appear in shades of blue or black, as the filter only allows blue light to pass through while blocking other colors. When viewed through a cyan filter, objects will appear in shades of cyan, blue, or black since the filter allows both blue and green light to pass, but blocks red light. Therefore, everything will predominantly show blue tones through both filters, with the cyan filter introducing some greenish hues as well.
